Definitions
- This invention relates generally to a dispenser of the pressure accumulating type, and is an improvement over my earlier U.S. Pat. No. 4,050,613. More particularly, the present pump includes a modified plunger/accumulator designed to avoid unwanted dribbles or drips after the discharge passage is thereby closed.
- Dispensers and sprayers of the pressure accumulating type have a plunger member which reciprocates on a hollow stationary piston in response to the force of return spring from below and hydraulic force from above.
- the plunger functions as a discharge valve which closes in response to spring pressure as it returns to its seated position against the underside of the plunger head, the discharge passage being formed in the plunger head and extending to the atmosphere from an accumulation chamber defined by a downwardly directed blind socket formed at the underside of the plunger head for snugly slidably receiving the plunger.
- dispensing pump operates quite efficiently and effectively in discharging product after the discharge is closed, an optional approach is available for avoiding any unexpected discharge at the commencement of the recharge stroke of the plunger.
- the plunger head of the example the pump according to the aforementioned application or my earlier patent U.S. Pat. No. 4,050,613 is subjected to lateral or eccentric forces during the dispensing operation, as when the operator reciprocates the head non-axially, such forces tend to induce a frictional load between the plunger and discharge valve elements which can permit the plunger-discharge valve to be momentarily held open at the end of the plunger downstroke with a small quantity of product remaining within the discharge passage.
- the actuating force on the head is relieved, even slightly, the frictional holding force or brake on the plunger is relaxed. This then causes the return spring to shift the plunger immediately to its discharge valve closing position.
- the plunger member is partially or wholly unrestrained by frictional engagement due to opposing force couples or lateral pressure acting on the head, then it will respond continuously and promptly in the intended operating mode in balance between the hydraulic pressure and the opposing spring force.
- the dispensing pump of the aforementioned application carries a contoured surface interfacing the stationary piston as an integral part of the plunger head.
- a contoured surface interfacing the stationary piston as an integral part of the plunger head.
- the plunger head reaches the bottom of its stroke while the plunger is still in the valve open mode, displaced from the seat in the head, and continuing the discharge at rated pressure, expelling the accumulated product as the spring force returns the plunger to its seated, valve closed position against the interior of the head.
- Another object of this invention is to provide such a pump wherein the plunger is isolated from lateral or eccentric forces which may be applied to the plunger head, so that the plunger which functions as a discharge valve is free from restraint by frictional engagement due to opposing force couples or lateral pressure and will therefore respond continuously and promptly in the intended operating mode in balance between the hydraulic pressure and opposing spring force.
- a further object of this invention is to provide such a dispensing pump as having spaced bearing members for guiding the plunger head to effect isolation of the plunger during pump operation.
- a still further object of the present invention is to provide such a dispensing pump wherein skirt means on or engaging the plunger head carry such bearing members to effect an unrestrained reciprocation of the plunger.
- a still further object of this invention is to provide such a dispensing pump wherein the skirt means comprise concentric skirts which extend from the plunger head and carry the bearing members.
- a still further object of the present invention is to provide such a dispensing pump wherein one of the bearing members is carried by an upstanding collar or skirt on the pump body which engages the head.
- a still further object of this invention is to provide such a pump wherein the skirt means comprises a plunger skirt which itself carries the bearing members, or wherein one of such bearing members is carried by an upstanding collar or skirt on the pump body which engages such skirt.
- a still further object of this invention is to provide such a dispensing pump wherein the upper end of the plunger has a wall defining a surface facing the upper end of the piston and complementarily contoured to at least the lip seal portion thereof, the wall having at least one part therein for maintaining communication between the pump and accumulation chambers, and the wall permitting the plunger to bottom out against the upper end of the piston before the end of the plunger head downstroke thereby allowing for further depression of the head so that it will continue to expel product through the discharge passage upon further depression thereof as the plunger moves into its discharge closing position.
- FIG. 1 is a vertical sectional view of one embodiment of a dispensing pump according to the invention.
- FIGS. 2 to 6 are half-section views similar to FIG. 1 of further embodiments according to the invention.
- FIG. 1 illustrates a pump assembly, generally designated 10, of the pressure accumulating type which is structured and functions similar to that of the aforementioned patent application and to that shown in my prior U.S. Pat. No. 4,050,613.
- the entirety of this patent is therefore specifically incorporated herein by reference.
- the pump assembly comprises a pump body 11 which includes an integrally formed closure cap 12 which may be internally threaded for securing the pump body in a liquid tight manner over the similarly threaded neck of a container (not shown), which is adapted to hold a flowable product to be dispensed by the pump.
- closure cap may be adapted for snapping it in place over the opening of the container, or the cap may be separate from the pump body for snapping or threading it in place.
- An annular sleeve 13 depends from an upper wall 14 of the pump body and extends into the container neck for enhancing the fluid tight seal between the pump body and the container.
- a stationary, hollow upstanding piston 15 is integrally formed on upper wall 14 via an annular wall which surrounds the base of the piston in spaced relationship and defines together therewith a container vent chamber 17.
- the piston has an inlet passage 18 extending therethrough into which a conventional dip tube 19 is coupled in any normal manner, the dip tube having its lower end extending into the product to be dispensed from the container.
- a ball check valve 21 and ball seat 22 are provided at the upper end of the piston for valve controlling the inlet passage, and a plurality of ball retention fingers 23 surround the ball check valve in spaced relation to permit unseating thereof during the suction stroke.
- the upper end of the piston terminates in an annular lip seal 24 which flares slightly outwardly in the normal manner.
- At least one container vent opening 25 is located in a lower portion of the vent passage and facilitates equalization of pressures within and outside the container as in the conventional manner so as to replace the product dispensed from the container with air to avoid collapse of the container and a vacuum lock condition within the pump.
- An annular plunger or accumulator 26 surrounds the pump piston, snugly embraces the same at its lip seal 24 and reciprocates relative thereto so as to therewith define a variable volume pump chamber 27.
- a return spring 28 extending between the underside of the plunger and a shoulder 29 formed on the pump body resiliently urges the plunger upwardly toward a fully raised position above the pump body.
- a plunger head 31 has a downwardly directed blind socket 32 which snugly and slidably receives plunger 26 and defines therewith an enclosed variable volume accumulation chamber 33 in open communication with pump chamber 27.
- This accumulation chamber has an appropriately larger diameter than the pump chamber, and the annular upwardly presented end of the plunger is exposed to downward fluid pressure within the accumulation chamber in opposition to the upward thrust of return spring 28.
- the plunger head is conformed to present an upwardly directed finger piece 34 so that intermittent finger pressure conveniently applied to it may be transmitted to the plunger for producing reciprocation thereof on stationary piston 15, each depression of the plunger being yieldably resisted by spring 28 which returns the plunger to its fully raised position each time finger pressure on the head is relieved.
- the plunger has an outer, annular depending skirt 35 terminating in an outwardly extending retention bead 36 which is outwardly dimensioned to be guided as it slides along the inner surface of an upstanding collar or skirt 37 on the pump body.
- the upper end of collar 37 has an inwardly extending retention bead 38 which cooperates with bead 36 for limiting upward movement of the plunger head at the predetermined position.
- these retention beads, or stop shoulders need not sealingly interengage since leakage of product through the container vent opening in the raised position of the plunger and plunger head shown in FIG. 1, is otherwise positively prevented.
- the plunger head includes a discharge passage 39 which terminates in a discharge orifice 41 and which extends from a discharge chamber 42 defined by the space between the plunger and plunger head.
- the upper end of the plunger head carries a contoured surface 43 as an integral part of the head and projects into pump chamber 27 partially displacing the air volume therein.
- This contoured surface is shaped to match the contour at the upper end of the piston, including the ball check valve and ball retention fingers as well as lip seal 24.
- the upper end of the piston and the opposing inner end of the plunger head are complementarily contoured so that when brought into face-to-face contact during a depression of the head, before the dispensing operation, any air which accumulated in pump chamber 27 is substantially purged by venting it through the discharge as that air is compressed and acts on the larger diameter accumulation chamber so as to shift the plunger relative to the discharge for the opening of same.
- vent chamber 17 The opening and closing of vent chamber 17 during plunger reciprocation is carried out in substantially the same manner as that disclosed for the pumps shown in my parent application Ser. No. 121,223.
- annular vent skirt 44 which controls the opening and closing of the vent, depends from the plunger head, rather than from the plunger, and terminates in an annular vent seal 45 which sealingly engages the inner surface of wall 16, as shown in the upwardly extended, vent closed position of FIG. 1.
- This inner surface 46 may have a slightly outwardly conical taper as it extends from the upper to the lower ends of the vent chamber so that a gradually increasing annular gap is formed between vent seal 45 and surface 46 as the plunger extends to its phantom outline position upon depression of the head. In this position, the container interior communicates with the atmosphere through vent opening 25 and open vent passage 17 outwardly of the pump.
- the upper end of the plunger or accumulator 26 may be similarly designed as in the FIGS. 5 and 6 pumps of my parent application Ser. No. 121,223.
- an outwardly extending flange 47 at the upper end of the plunger is seated on the outer surface of a ring 48, depending from the upper end of the plunger head, in the fully raised and discharge valve closing position of the plunger of FIG. 1.
- the lower end of the plunger is reversely bent to define a lip seal 49 in sealing engagement with the inner surface of the head bore which may also incorporate vent skirt 44, and delimiting discharge chamber 42.
- the terminal end of lip seal 49 lies below discharge passage 39 so that only a slight relative shifting between the plunger and the head opens the discharge as flange 47 is moved away from ring 48. A quick opening discharge is therefore made possible.
- vent skirt 44 functions within the vent chamber together with and in response to reciprocation of the plunger head.
- vent skirt 44 serves also as an aligning element together with retention bead 36 which respectively glide along inner surface 46 and the inner surface of collar 37.
- the plunger head is permitted to reciprocate axially between stop limits while being maintained with its axis congruent with the pump body axis including especially collar 37, the vent passage, and the stationary piston portions.
- the plunger head can experience various non-axial forces without cocking its axis, or otherwise losing axial congruency. Therefore, the mis-application of lateral or eccentric forces to the plunger head during reciprocation is prevented from transmitting any bias or restraining force to the plunger.
- the plunger which functions as the discharge valve and pressure regulating element, is free floating between the spring force below and the hydraulic force above and is not restrained against movement in response to these forces.
- Pump assembly 10A shown in FIG. 2, is the same in most respects to that of pump assembly 10 so that like elements will be represented by the same reference numerals.
- plunger/accumulator 26a is structured so that, in addition to its free floating characteristic allowing it to reseat itself under the plunger head at the end of the plunger downstroke and before the ensuing plunger recharge stroke to avoid a discharge spurt after recharge commences, product is assured of being purged from the accumulation chamber before commencement of the recharge stroke.
- an air displacement interfacing contoured surface 43a identical to surface 43 of FIG. 1, is disposed at the upper end of the plunger as an integral part thereof.
- This surface includes a cover wall slightly spaced as at 51 from the underside of the plunger head and including at least one through port 52 for maintaining the open communication between the pump chamber and the accumulation chamber.
- this interfacing contour of the head projects into the open upper end of the plunger so that the head interior bottoms against the upper end of the stationary piston and ball check members at the end of the discharge stroke.
- the interfacing contour may thus reach the bottom of the discharge stroke while the plunger is still in a discharge valve open mode, displaced from the seat in the head, and continuing the discharge at rated pressure, expelling the accumulated product as the spring force returns the accumulator to its seated, valve closed position against the interior of the head. This continued discharge as the valve closes is referred to above as "after spray”.
- the plunger member without vent skirt and with the interfering air displacement integral contour becomes a free floating member responding to the opposing hydraulic and spring forces plus normal frictional factors.
- the plunger head carries annular vent skirt 44 having a vent seal 45 which engages inner surface 46 of the vent chamber as a vent valving member, and which also serves as an alignment guide cooperating with head retention bead 36 as bearing members spaced apart axially to resist lateral or eccentric forces on the plunger head, and to isolate such forces from the plunger/accumulator.
- Pump assembly 10B of FIG. 3 is similar to that of assembly 10A of FIG. 2 in that contoured surface 43b, having at least one through port 52 therein, is disposed at the upper end of plunger 26b as an integral part thereof.
- This plunger has an annular discharge flange 53 with an upper end lying slightly above discharge passage 39 for opening same more slowly during relative reciprocation between the plunger and the piston, similarly as in FIG. 1 of my aforementioned parent application.
- plunger 26b, with its interfacing contoured surface 43b functions the same and achieves the same results as plunger 26a and its contoured surface described with reference to FIG. 2.
- FIG. 3 plunger head includes a vent skirt 44b which forms an extension of plunger skirt 35 so as to together define a single skirt which carries retention bead 36 and vent seal 45 which respectively glide along the inner surface of collar 37 and along inner surface 46.
- Bead 36 and vent seal 45 also serve as spaced bearing members to resist lateral or eccentric forces on the plunger head, as described in detail with reference to FIGS. 1 and 2.
- pump assembly 10C of FIG. 4 is the same as assembly 10B of FIG. 3 except that retention bead 38, rather than bead 36, functions as a bearing member as it is guided along the outer surface of skirt 35 during plunger reciprocation.
- Pump assembly 10D of FIG. 5 is essentially the same as that disclosed in the aforementioned parent application in that vent skirt 44d extends from plunger 26d for performing the venting function as therein described.
- contoured surface 43d identical to surface 43a of FIG. 2, is disposed at the upper end of plunger 26d as an integral part thereof and functions in the identical manner as that described with reference to FIG. 2.
- Pump assembly 10E of FIG. 6 is essentially the same as assembly 10D except that retention bead 38 glides along the outer surface of skirt 35 to thereby function in the same manner as that described with reference to FIG. 4.
- a contoured surface 43e is disposed at the upper end of plunger 26e as an integral part thereof and functions in the same manner as that described with reference to FIG. 2 except that a central contoured portion 43e, which matches the ball check valve, is located on the underside of the plunger head.
- the plunger/accumulator is developed as free floating and/or having at its upper end an air displacement interfacing contour for assuring continuous and quick response in the intended operating mode and for mechanically effecting a discharge valve closing assist at the end of the plunger discharge stroke.
